Publication number: 20030139337Abstract: Openings in a mammalian body made by any medical procedure or non-medical event are sealed with a bioabsorbable plug or sewn with a bioabsorbable suture. In one exemplary embodiment, the plug in dehydrated, unexpanded condition is pushed by a pushing device through the lumen of a needle until a first part of the plug is external to the opening and a second part is internal to the opening. The needle is then withdrawn while the position of the pushing device is maintained. The pushing device is then withdrawn, leaving the plug in sealing relation to the opening. The body's moisture causes the plug to expand to complete the sealing of the opening, or the expansion may be caused by exposure to air, light, or other stimulant. The opening may be formed in soft tissue, internal organs, or hard tissue. The plug seals the flow of liquid or gaseous biological fluids.Type: ApplicationFiled: March 27, 2003Publication date: July 24, 2003Inventors: John S. Fisher , Frederick Ahari , Lucjan J.J. Hronowski

Publication number: 20030125639Abstract: A biopsy tool that performs a biopsy and a complete removal of a tumor or lesion in a single step. A hollow pointed needle having a cylindrical lumen has an inner tube mounted for rotation in the lumen. A slot is formed in the hollow needle in a sidewall of the needle and an opening having sharp peripheral edges is formed in the inner tube. A vacuum is applied to the lumen of the hollow needle to pull tissue into the slot during a biopsy procedure. Rotation of the inner tube shears off a slice of tissue and the vacuum pulls the slice of tissue to a remote collection point. Each rotation of the inner tube removes an additional slice of tissue so that an entire lesion or tumor is removed in a short period of time. The sliced tissue is undamaged and suitable for use as a biopsy sample for diagnostic purposes.Type: ApplicationFiled: January 2, 2002Publication date: July 3, 2003Inventors: John S. Fisher, Frederick Ahari

Patent number: 6264685Abstract: A flexible high radial strength stent comprising one or more flex cells and primary cells. The primary cells comprising elongated members having first and second ends and extending in a circumferential direction around an axis and curving in two opposite directions transverse to the circumferential direction. The elongated members are joined to one another on their first ends forming cusps. The flex cell may comprise a member in the shape of a U, V, ellipse, rhombus, parallelogram, or other similar shape. The flex cell has two ends, or in the case of the parallelogram two vertices, each of which is attached to the adjacent second end of a neighboring elongated member.Type: GrantFiled: July 6, 1999Date of Patent: July 24, 2001Assignee: Datascope Investment Corp.Inventor: Frederick Ahari

Patent number: 6102942Abstract: A stent/graft deployment catheter which deploys a stent/graft by pulling it out of its delivery sheath rather than pushing it out. The stent/graft deployment catheter comprises a tip capable of positively engaging a distal end of a stent/graft. Said tip houses a pair of ball bearings which engage a notch in the inner surface of the stent/graft when the inner lumen is occupied by a guide wire.Type: GrantFiled: March 30, 1998Date of Patent: August 15, 2000Assignee: Endovascular Technologies, Inc.Inventor: Frederick Ahari

Patent number: 5944727Abstract: A stent/graft catheter delivery handle comprising a housing and a trigger pivotally connected to the housing on one end of the trigger. Squeezing the free end of the trigger towards the handle housing shifts a pawl, which is engaged with grooves on the outer surface of a stent/graft delivery catheter, longitudinally along the length of the catheter. Shifting of the pawl has the effect of retracting the sheath of the catheter relative to the plunger (inner lumen assembly) of the catheter and thus deploying a stent/graft stored in a proximal end of the catheter.Type: GrantFiled: September 2, 1998Date of Patent: August 31, 1999Assignee: Datascope Investment Corp.Inventors: Frederick Ahari, Jody W. Stallings, Richard C. Fortier, Bruce Adams

Patent number: 5425738Abstract: An endoscopic insertion device for inserting an anastomosis ring having two unitary members in an anatomic tubular body member comprises an anastomosis ring adapter for mounting the unitary members in an engaging position, an inserter for inserting the ring adapter in the tubular body member, and an actuator for actuating the adapter to close the anastomosis ring. A method of using the endoscopic insertion device includes the steps of inserting the anastomosis ring in an engaged position into the tubular body member, securing opposite ends of the tubular body member to the engaged anastomosis ring, applying a biasing force to close the anastomosis ring, releasing the biasing force, and axially withdrawing the insertion device from the closed anastomosis ring.Type: GrantFiled: October 18, 1993Date of Patent: June 20, 1995Assignee: American Cyanamid CompanyInventors: Scott B. Gustafson, Frederick Ahari, William J. Allen, George Jessup, John F. Howard, Harold S. Terk, Lester F. Miller
